pyarango driver for arangoDB: validation

I am using pyarango driver (https://github.com/tariqdaouda/pyArango) for arangoDB, but I cannot understand how the field validation works. I have set the fields of a collection as in the github example:

ArangoDB as document store itself doesn't enforce schemas, neither do the drivers.
If you need schema validation, this can be done on top of the driver or inside of ArangoDB using a Foxx service (via the joi validation library).
